Technologies for freshwater augmentation are wide and varied
making it impossible for this source book to cover them all. This Source Book
attempts to cover those technologies that are African, traditional and unique.
Periodic reviews of the included technologies will be necessary. Part B covers
these technologies in three sectors: agriculture, domestic water supply, and
mining and industry. Each technology is classified according to its application
within that sector. Four key areas of application have been used for this
classification: water harvesting; water quality upgrading; water conservation;
wastewater recycling and reuse. Some technologies may be used in more than one
sector and this will be indicated
accordingly.
